Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a vital role in various bodily functions [1]. It is essential for nerve tissue health, brain function, and the production of red blood cells [2]. Vitamin B12 is not produced by the body itself; it must be obtained through diet or supplements [3].
The main components of Vitamin B12 are a cobalt ion surrounded by a corrin ring [4]. The source of Vitamin B12 is primarily from microorganisms, such as bacteria and archaea [5]. Animals obtain Vitamin B12 by consuming these microorganisms, and humans can then acquire it by eating animal products like meat, fish, and dairy [6]. Fortified foods and supplements are also common sources of Vitamin B12, especially for individuals who follow vegetarian or vegan diets [7].
Vitamin B12 is widely used in the food and beverage industry as a nutritional additive [8]. It is incorporated into foods such as breakfast cereals, energy drinks, and plant-based milk alternatives to enhance their nutritional value [9]. In the supplement industry, Vitamin B12 is available in various forms, including tablets, capsules, and injections, to address deficiencies and support overall health [10].
The industrial production of Vitamin B12 typically involves bacterial fermentation [11]. Specific strains of bacteria, such as Propionibacterium and Pseudomonas, are cultivated in large fermentation tanks, where they produce Vitamin B12 as a byproduct of their metabolism [12]. The Vitamin B12 is then extracted from the fermentation broth, purified, and crystallized [13]. The resulting crystals are dried and milled to the desired particle size [14]. Quality control testing, including HPLC analysis, ensures that the final product meets purity and potency standards [15].
Vitamin B12 finds applications in various scenarios, most notably in addressing dietary deficiencies, supporting neurological health, and boosting energy levels [16]. It is commonly used in supplements designed for vegetarians and vegans, who are at higher risk of Vitamin B12 deficiency due to the absence of animal products in their diets [17]. It is also used in medical settings to treat conditions such as pernicious anemia and nerve damage caused by Vitamin B12 deficiency [18]. Additionally, Vitamin B12 is added to certain food products to enhance their nutritional profile and appeal to health-conscious consumers [19].
Vitamin B12 is typically packaged in airtight containers to protect it from light and moisture [20]. It should be stored in a cool, dry place, away from direct sunlight, to maintain its stability and potency [21]. Under proper storage conditions, Vitamin B12 has a shelf life of approximately two years [22]. It is important to adhere to the manufacturer's recommended storage guidelines to ensure the quality and effectiveness of the product [23].
